Voice over IP (VoIP)
all licences are occupied currently, the SIP subscriber can only make emergency
calls.
When a SIP subscriber logs off, when terminating the programme, for example, the
associated licence will become available immediately. A licence is also made
available when a SIP subscriber's regular status query is not conducted. The
internal clock for automatic log-out is determined by the Profile assigned under
PBX Configuration: Devices: VoIP Phones. The (Keepalive) internal clock setting
is located on the PBX Configuration: System: VoIP profile page.
Detailed information on the current licence assignment and on logged-on SIP sub-
scribers is located on the System Info: PBX: SIP phones page. This page is where
you can reset licence assignment at any time by clicking on Reset licences.
